| Title | Discovery Of After-The-Fact Emergency Condition: Inapproriate Change Made To Emergency Action Level 3J Back In 1997 Caused An Emergency, Alert, Not To Be Declared. |
| Event Description | On 9/08/2006 at 1015 during painting activities in a safety-related area the Methanol Short Term Exposure Limit was exceeded. In accordance with Callaway Plant procedures the location was determined to contain a Hazardous ATMOSPHERE. Subsequently, Callaway Plant Emergency Action Levels (EAL) were reviewed and it was determined that the event did not meet the EAL criteria for Callaway Plant EAL 3J related to release of flammable or toxic gases in a safety - related area.
On 9/21/2006 following a debrief that was conducted by Region IV NRC personnel, it was determined at 1025 that an inappropriate change to the intent of EAL 3J was made in 1997. As a result of this discussion, it was determined that an Alert should have been declared in accordance with plant EAL 3J. Per guidance given in NUREG 1022, Revision 2, Section 3.1.1. "Immediate Notifications", an ENS notification is being made within one hour of discovery of the event. No actual declaration of the emergency class will be made since the event has been concluded and the basis for the emergency no longer exists. The NRC Resident Inspector has been notified." Licensee also notified State, Local Officials and other government agencies. |
